A seed potato with short sturdy shoots looks very different from a forgotten kitchen potato with long pale sprouts. Chitting is a deliberate preparation step, not simply leaving tubers in a dark cupboard until something happens.
The RHS potato-growing guide describes chitting as an optional head start that is particularly useful for early varieties. It is not essential, and a planting calendar written for the UK needs adjustment for another climate.
Set up a small, labelled tray
- Start with suitable seed potatoes from a reputable source. Keep the variety information.
- Arrange them with the eyes facing upward in egg cartons or another stable tray.
- Place them somewhere cool, bright and frost-free, following the supplier’s guidance.
- Check periodically and handle emerging shoots gently rather than repeatedly turning the tubers.
The practical aim is short, manageable growth. If the shoots become long and weak, review the light and storage conditions rather than assuming that more length means a better start.
Keep the planting decision separate
Ready-looking sprouts do not make cold or unsuitable ground ready. Check local planting advice, soil conditions and frost risk. The variety and your growing method also affect timing. Do not use one calendar date as a universal instruction.
For an invented record, label two varieties with the date you began chitting and note when each was planted. Later, compare emergence and harvest timing without claiming that chitting alone caused every difference. Weather, soil and variety are also involved.
At planting, avoid knocking the shoots off as you move the tubers from tray to bed. Follow the spacing and depth advice appropriate to the variety and conditions. Keep seed potatoes separate from food potatoes so nobody mistakes the prepared tubers for ingredients.
A tray on a bright shelf is useful because it makes the preparation visible and controlled. The final question remains practical: can these tubers be planted into suitable conditions without damaging the growth you have carefully encouraged?
